Inventor r I "I Attorneys OAS w. cook, or MATHIS, 'rnxnsz' MACHINE FOR CLEANING AND FEEDING COTTON.

Specification of Letters Patent.

Patented Nov. 18, 1913.

Application filed September 28, 1912. Serial No. 722,905.

To all whom it may concern:

Be it known that 1, Gas W. Coon, a citizen of the United States, residing at Mathis,

in the county-of San Patricio and State of 7 this character having sight openingstherein whereby the contents thereof can be readily viewed at all times.

A further object is to provide a combined cleaner and feeder the cylinders of which can be easily removed and replaced.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the comination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without.

departing from the spirit of the invention.-

In the accompanying drawings the .pre-' ferred form of the invention has been shown.

In said drawings :Figure l is a side elevation of the machine. Fig. 2 is a vertical longitudinal section therethrough.

Referring to the figures by characters of reference 1 designates a casin having an inclined bottom 2. Arranged a ove the upper end of this inclined bottom is a feed chute 3 adapted to discharge cotton into the casing and located at the lower end of the bot tom 2 is a trough 4 in which a suitable conveyer not shown, is adapted to be located.

Extending transversely of the casing ll and below the feed chute 3 is a concaved screen 5 and another concaved screen 6 is located in the casing and above the trou h 4, this last named screen extending, at Its discharge end, up to the outlet opening 7 of the casing and which is arranged beyond but above the trough .4. A desired number of additional concaved screens 81s interposed between the screens 5 and 6 and all of these screens extend transversely ofthe casing 1 and are spaced above the bottom 2. Interpcsed between the concaved screens areoutlet passages 9- extending throughout the width of the casing and discharging downwardly onto the inclined bottom 2, the lower ends of these passages being supported abov the bottom so as to permit objects to pass' freely under them.

Extending transversely of the upper portion of casing 1 and directly abovethe passages 9 are cross bars 10. Each of these cross bars has an arcuate closure 11 hingedliy connected thereto, as at 12 and provided, a jacent its center, with a sight opening 13 closed by a transparent plate 14.

Curved slots 15 are formed in the sides of :thecasing l and receive the gudgeons 16 of feed drums 17 these gudgeons normally bearing upon the inner end walls of the slots, thus to support the drums close to but out of contact with the concaved screens. Teeth 18 extend radially from the drum and travel close to the screens 5, 6 and 8. Secured to one gudgeon 16 of each drum 17 is a pulley 19 and these pulleys are engaged by an endless belt 20, the upper run of the belt being extended under idler pulleys 21 which are interposed between the pulleys 19 as shown in Fig. 1.

Arranged within the chute 3 and above the feed drum 17 in the lower portion of the chute are oppositely disposed feed rolls 22 extending throughout the width of the chute, each of these rolls having a gear 23 revoluble therewith and the two gears con:

- stantly meshing, as shown in Fi 1. Any

suitable means may be provided or driving the gears 23 and for actuating the belt 20. By varying the speed of rotation of the rolls 22, the feeding of cotton to the apparatus can be controlled.

Secured to the top of the casing 1, ad athe cross bars, are curved deflectors 24 whichv overhang the drums 17. The functionof these deflectors 24 is to prevent cotton from being thrown too far upon the pcriphery of one drum, by the action of the preccdingdrum. Any one drum, considered as a receiving drum, will not, therefore,

throw the cotton back upon the preceding drum, which may be consldered as-the delivering drum. Located in the'outlet 7 is another. curved deflector 25, which acts to retard the cotton on the last drum so as to pull'it therefrom and drop it into the trough 4..

Resilient means is provided for holding the several drums 17 depressed so that -they Will cooperate with the screens 8, the construction-bei'ng such that the drums 17 may rise when a quantity of cotton accumulates 7 between the screen 8. and the peripheries of the drums. This resilient means may be of any form but in the present instance, the same comprises spring arms 26, secured to the casing l, and bearing upon the gudgeons 16 of the drums 17 and serving to hold the drums down for the purpose hereinbefore set forth. The gudgeons of the uppermost drum may, if desired, be mounted to recip rocate in a slot 27 formed in the side walls of the chute 3.

It will be seen that all of the drums 17 rotate in the same direction, as indicated by the arrows in Fig. 2 and the cotton fed to the upper drum 17 by the rolls 22 will be engaged by the teeth 18 on said drum and carried over the concaved screen 5.. Any dirt or the like mixed with the cotton will fall through the screen 5 andonto the inclined bottom. The cotton will be thrown across the adjacent passage 9 and. against the next adjoining drum 17 where it will be again engaged by the teeth on said drum and carried over the concaved screen 8. The cotton is then thrown to the next drum and this operation is repeated throughout the length of the apparatus until finally the cotton is discharged through the opening 7. As the cotton is drawn over the various concaved screens, small particles of dirt will drop .through the screen and'onto the bottom 2 and will gravitate from said bottom onto the bottom 2 and will gravitate from said bottom to the trough 4. As the cotton is passing over the passages 9, any large particles such as stones, pieces of metal or the like, will fall into said passages and be di rected onto the inclined bottom 2 so as to' slide downwardly into the trough 4.

From the foregoing it will be apparent that cotton, when acted upon in the manner set forth, will be thoroughly cleaned of all dirt, hulls, twigs and similar trash and, furthermore, all large heavy particles which,

may become accidentally mixed with the cotton will likewise be removed. The contents of the apparatus can be easily seen at any 56, time by looking through the plates 14.

Should any large objectionable particles become lodged between one of the drums and "the concaved screen thereunder, the closure 11 above said'drum can be opened and the drum elevated from the screen by shifting casing having a trough at one end and a bottom inclined downwardly tothe trough, there being a cotton outlet adjacent the trough, concaved screens located above the inclined bottom and the trough, there being outletpassages between the screens" and discharging onto the inclined bottom, toothed drums mounted for rotation. above the screens, curved deflectors overhanging portions of the respective drums, and a cotton retarding element supported above the out- 1 let for engagingcotton upon one of the drums 2. A cotton cleaner and feeder including a casing having a trough at one end and a bottom inclined downwardly to the trough, there being a cotton outlet adjacent the trough, concaved screens located above the inclined bottom and the trough, there being outlet passages between the screens and discharging onto the inclined bottom, toothed drums mounted for rotation. above the screens, curved deflectors overhanging portions of the respective drums, a cotton retardingelement supported above the outlet for engaging cotton upon one of the drums, and'a closure upon the casing and above each drum, said closures being separably movable... 5

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
